Trouble description
Details to be checked
Confirmation method
Data link cannot
be stopped.
Is the data link stop (SB0002) ON?
Confirm the sequence program.
Has an error occurred?
Check the data link stop result
(SW0045).
Data link cannot
be restarted.
Is the data link stop (SB0000) ON?
Confirm the sequence program.
Has an error occurred?
Check the data link restart result
(SW0041).
Parameters cannot
be registered to
the EEPROM.
Is the write request for parameter
registration to EEPROM (BFM# A
H
b10)
ON?
Confirm the sequence program.
Has an error occurred?
Check the EEPROM registration status
(SW00B9).
A remote station
cannot start up.
Are the settings consistent between the
station information (parameter) and the
remote station?
Confirm the contents of the parameters.
Does the station number overlap with
another module?
Check the station number setting
switch.
Faulty stations
cannot be
detected.
Are stations specified as error invalid
ones?
Confirm the contents of the parameters.
Does the station number overlap?
Check the station number
Faulty stations
occur depending
on the
transmission
speed.
Can faulty stations be detected by the
communication status in other stations
(SW0080)?
•
Check the switch settings in the
faulty station.
•
Check whether the cable wiring is
correct.
•
Check whether the cable shield is
grounded.
Is normal communication established
when the transmission speed is slowed
(to 156 kbps, for example)?
